i have just started on midodrine to help with my POTs condition I have been on it 3 weeks now but since starting it I feel continuously tired, I have lost my appetite, I have a continuous headache and feel quite down and can not get up and going which is not normally like me at all, I have also had some of the other side effects as well but not so worried about them, just want to know is this normal, if so how long does it last as I am really thinking about stopping it as although the alternate of passing out is not much better at least I felt semi ok before taking it , please help regards Pauline x
